I am a Associate Research Scientist
Henry A. Rowland Department of Physics and Astronomy
of The Johns Hopkins University
and I work with the
X-ray Laboratory of the
Astrophysics Science Division of the
Goddard Space Flight Center.
I work with data from
My interests lie primarily in the study of the hot Galactic ISM
using X-ray observations,
and I am particularly interested in isolating
and studying the hot Galactic halo.
Understanding the extent and nature of the hot Galactic halo
places constraints on models of galaxy formation
and will be crucial for studies of the Warm-Hot Intergalactic Medium.
In classical ISM studies, X-ray observations directly
address such active questions as the filling factor of hot gas.
Isolating the hot galactic halo requires
characterization of the Galactic foreground components
such as the Local Hot Bubble and the Galactic bulge
by a combination of absorption and broad-band photometric techniques.
The current generation of X-ray instruments makes possible
isolation of the various components by spectroscopic techniques,
given long exposures and accurate instrumental background calibration.
I am currently using a combination of Guest Observer observations
and archival data from Chandra and XMM-Newton
to study the Local Hot Bubble, the Galactic bulge,
and the Loop I superbubble in preparation for a large-scale study
of the Galactic halo.
In parallel, I am pursuing a study of the diffuse X-ray
emission in galaxies similar to the Milky Way
in order to constrain the amounts/types of emission
from various structural components; arms, bulge,
extended spheroid, etc..
This study has recently led to an excursion into
the HST optical identification of X-ray point sources
in M101 in order to determine the distribution of
sources among Low-Mass X-ray binaries, High-Mass X-ray binaries,
and background AGN.
